本学位论文主要针对在HCl存在下以氧化锰修饰的二氧化铈纳米棒为催化剂的乙烷氧化脱氢制乙烯的催化体系开展了深入研究。论文从催化剂性能、结构特征以及反应机理等方面进行探讨。 CeO2纳米棒是HCl存在下乙烷氧化脱氢制乙烯的有效催化剂。对CeO2纳米棒的修饰可以进一步提高其催化性能，其中在经Mn修饰制备的Mn-CeO2纳米棒催化剂上可以获得较高的C2H6的转化率和C2H4的选择性。在8Mn-CeO2纳米棒上，当乙烷转化率为94%时，C2H4选择性为69%。经过100h寿命测试，该催化剂上乙烷转化率稳定在90%以上，C2H4选择性约为75%，C2H4收率保持在65%以上。 针对HCl存在下乙烷氧化...This dissertation contributes to studies on the oxidative dehydrogenation of ethane to ethylene in the presence of HCl under moderate temperatures. Structure and catalytic performances of catalysts for this reactions was investigated in detail. Reaction mechanism were also discussed. CeO2 nanorods was an excellent catalyst for the oxidative dehydrogenation of ethane to ethylene in the presence o...学位：理学硕士院系专业：化学化工学院_物理化学(含化学物理)学号：2052011115166
